On asymptotic properties of an estimate of a functional of a probability density

Abstract

Bhattacharyya & Roussas (1969) proposed to estimate the functional Δ = ∫ _?∞/^∞ f ²(x)dx by , where is a kernel estimate of the probability density f(x). Schuster (1974) proposed, alternatively, to estimate Δ by , where F _n (x) is the sample distribution function, and showed that the two estimates attain the same rate of strong convergence to Δ. In this note, two large sample properties of are presented, first strong convergence of to Δ is established under less assumptions than those of Schuster (1974), and second the asymptotic normality of established.     

Does order flow in the European Carbon Futures Market reveal information?

This paper identifies the classes of agents at play in the European Carbon Futures Market and analyzes their trading behaviour during the market's early development period. A number of hypotheses related to microstructure are tested using enhanced ACD models. Evidence is presented that the market is characterized by three different groups of traders: informed, fundamental, and uninformed. OTC trades are distinct to regular trades and are used strategically by the informed. Fundamental traders react faster in Phase II and the informed counteract by increasing their trade size and speed. The results indicate enhanced market transparency and increased market maturity.     

Imputation methods of missing data for estimating the population mean using simple random sampling with known correlation coefficient

This paper considers three ratio estimators of the population mean using known correlation coefficient between the study and auxiliary variables in simple random sample when some sample observations are missing. The suggested estimators are compared with the estimators of Singh and Horn (Metrika 51:267–276, 2000), Singh and Deo (Stat Pap 44:555–579, 2003) and Kadilar and Cingi (Commun Stat Theory Methods 37:2226–2236, 2008). They are compared with other imputation estimators based on the mean or a ratio. It is found that the suggested estimators are approximately unbiased for the population mean. Also, it turns out that the suggested estimators perform well when compared with the other estimators considered in this study.     

Currency crisis transmission through international trade

The Eurozone recent crisis has shown how balance of payments problems in less developed European Monetary Union (EMU) member countries can affect EMU trading partners, spreading the crisis to a larger group of countries. This paper introduces a three-country dynamic general equilibrium model to analyze whether and how terms of trade effects can generate a spillover effect or a currency crisis transmission between countries. Specifically, using a two period model, it incorporates world market clearing conditions for tradables into a new theoretic model, analyzes net capital flow movements between countries, and establishes cross-border macroeconomic linkages. This paper shows how a currency crisis can transmit through the real (trade) sector channel of the economy.     

Internationalisation,growth and pay inequality: a cointegration analysis for Turkey, 1970–2007

The nature of the internationalisation-growth-inequality nexus is very complex; and therefore, not surprisingly, there is no consensus on whether increasing openness to trade leads to higher inequality or not – in fact, there is even no full understanding on the impact of the openness on the economic growth. In the case of Turkey it is observed that there is relatively little empirical work that addresses the issue of inequality. Considering this fact, the study aims to provide some more evidence on the complex relationship between trade openness, foreign direct investment, economic growth and pay inequality by utilising a combination of different Theil Indices of pay inequality. The paper utilises the Johansen Cointegration and Granger Causality methods. Our findings yield that higher economic growth resulting from trade openness comes with higher pay inequality.     

Entrepreneurial intention among University students in Malaysia: integrating self-determination theory and the theory of planned behavior

The present study endeavors to develop a deeper understanding of the motivational processes involved in intentional entrepreneurial behavior. For this purpose, it integrates the social cognitive approach of the theory of planned behavior (TPB) and the organismic theory of motivation of self-determination theory (SDT). More specifically, it tests the role of basic psychological needs of autonomy, competence and relatedness as defined in SDT in shaping university students’ attitudes and intentions toward entrepreneurship. The sample of this study consisted of 438 (Males?=?166, Females =272) 3rd and 4th year university students from four Malaysian Public Universities. The results of the study show that the model strongly explains about 71% of the variance in entrepreneurial intention. Basic psychological needs of autonomy, competence and relatedness have a strong indirect impact on entrepreneurial intention via their attitudinal antecedents: attitude, subjective norm, and perceived behavioral control. This indicates a full-mediational model, where the attitudinal factors operated as transmitters of effects from the distal constructs of SDT on entrepreneurial intention. These findings confirm that both SDT and the TPB provide complementary explanations of the motivational processes of entrepreneurial behavior. The study contributes to the existing knowledge by providing a theory-based understanding of the role of motivations in the formation of entrepreneurial intentions. It opens the way for future research to analyze how alternative motivations may affect new venture creation, survival and success.

     

Managers’ Attitudes Toward Codes of Ethics: Are There Gender Differences?

As the need for more diversity in business ethics is becoming more pressing in our global world, we provide an historical study of a Fair Trade (FT) movement, born in rural Mexico. We first focus on the basic assumptions of its founders, which include a worker–priest, Frans van der Hoff, a group of native Indians and local farmers who formed a cooperative, and an NGO, Max Havelaar. We then review both the originalities and challenges of the FT movement and its potential contributions to the current theories and practices in business ethics.     

Gender diversity in the hospitality industry: An empirical study in Turkey

This paper, an investigation of gender diversity in the Turkish hospitality industry, focuses on two primary objectives: (a) exploring the potential relationships between gender and several demographic factors, and (b) examining the possible existence of a gender effect regarding employees’ perceptions of recruitment and earning potential decisions. Results, based on 682 surveys, show that, in the male-dominated Turkish hospitality industry, there is a significant gender effect for two of four demographic variables and with respect to recruiting efforts and earning potential. These findings could have some important managerial implications for addressing gender diversity in the (Turkish) hospitality industry.     

Does training benefits lead to acquisition of livelihood assets and change in social status? Evidence from training of rice farmers

Livelihood assets which are considered and recognised for their life-supporting role contribute significantly and basically to the standard of living of people. These contributions as deemed more meaningful are considered necessary to farmers whenever an opportunity exists to diversify their investment. This study looked at how the benefits from increase in farmers' rice yield contribute to farmers ability to acquire livelihood assets to enhance their standard of living. A sample size of 265 from a population of 880 farmers trained by Japan International Cooperation Agency on sustainable rainfed low-land rice production technology was used. The objective was to establish how proceeds from rice sale influenced the acquisition of livelihood assets by farmers to support their standard of living. Using spearman rho correlation, it was found that a strong positive correlation exists between increase rice output and livelihood assets acquisition. It is recommended that the technology should be disseminated nationwide specially in low-land rice farming areas so that all farmers in the country could benefit.     

A typology of Jordanian consumers after Covid-19: The rational,the suspicious,and the cautious consumer

This study presents a detailed typology of Jordanian consumers that identifies the effects of Covid-19 on their personal, social, and purchase and consumption patterns following the pandemic. Based on a qualitative approach using a sample of Jordanian consumers (N = 71), this study identifies three main types of consumers: the rational, suspicious, and cautious. All were distinguished by cognitive, emotional, and behavioral differences: the rational consumers viewed the pandemic as a natural occurrence, were willing to vaccinate, and took the opportunity to improve their lives and consumption behavior; the suspicious consumers viewed the pandemic as a man-made virus and refused to rationalize their behaviors and follow the social-distancing rules or vaccinate; and the cautious consumers were generally somewhere in between, and while they improved some aspects of their consumption, social, and personal lives, other aspects either remained the same or worsened. The findings have implications for managers and governmental bodies.
